Jacob S. ★★★★★

Finally, a pack of o-rings that actually fit snugly without stretching too much—the 70 durometer is spot-on for my hydraulic repair jobs. They've held up fine under some hot oil exposure, and the -40°F rating gives me peace of mind for winter use.

Owen C. ★★★★★

I’ve been using these dash 414 o-rings in a hot oil application around 200°F and they’re holding up perfectly without any swelling or leaks. The 70 durometer feels sturdy but still seals nicely against the groove.

Steven ★★★★★

They handled the -20°F startup just fine without getting brittle, and the 70 durometer feels firm but not too stiff for my standard hydraulic fittings. Exactly what I needed for the rebuild.
